In '99, it became a requirement to paint or permanently reidentify white conductors of multiconductor cables that are being used on switch loops as hots.
I think the "permanent" part of this excludes the use of tape.
Has anybody got a good way to do this?
I've been using a "paint pen" (like an enamel felt marker), and the wire's all sticky unless it's left for days and days.

In VA, we have been letting all use tape. It does not normally fall off, making it permanent as far as we are concerned.

If your area won't accept tape, how about a short length of PVC sleeving?

We often use red sleeves over blacks (normally neutral) here to identify switch loops. It's permanent in the sense that it won't come off unless you cut it or disconnect the wire from the switch terminal.

Use some shrink tube of different colors.

We have been using colored heat shrink on our orders going into the U.S. and it has been accepted through all the jurisdictions it doesn't come off without cutting the wire.

Thanks!
The heat shrink sounds like it would be a very good way for us to go.
The 3 wire cable (BX?) would be cost prohibitive for us. We do lots of offices, and unless the jobs require it (some occupancy sensors need the neut), the added $ would add up to quite a sizeable sum.(I already got shot down suggesting this)

Here's an idea that I heard on another BBS.

"Get a black Magic Marker (the mongo, chisel-point kind) and drill a hole through the tip. To re-identify a white, just run it through the hole. Faster than taping-and permanent."

I haven't tried it yet, but it sounds good to me.

Steve,

Because the Electrons will be confused by the change in Insulation color! [Linked Image]
That will make them stop moving.

I'm sorry, just couldn't resist that one!

Can't remember who it was that said it first [posted the response about Electrons being confused by the color of insulation], but it was - and still is - FUNNY!!!
